LD29080 SERIES 800mA FIXED AND ADJUSTABLE OUTPUT VERY LOW DROP VOLTAGE REGULATOR PRELIMINARY DATA s s s s s VERY LOW DROPOUT VOLTAGE (TYP. 0.4V AT 800mA) GUARANTEED OUTPUT CURRENT UP TO 800mA FIXED AND ADJUSTABLE OUTPUT VOLTAGE (±1% AT 25°C) INTERNAL CURRENT AND THERMAL LIMIT LOGIC CONTROLLED ELECTRONIC SHUTDOWN PPAK DPAK DESCRIPTION The LD29080 is a high current, high accuracy, low-dropout voltage regulators series. These regulators feature 400mV dropout voltages and very low ground current. Designed for high current loads, these devices also find applications in lower current, extremely low dropout-critical systems, where their tiny dropout voltage and ground current values are important attributes. Typical application are in Power supply switching post SOT-223 regulation, Series power supply for monitors, Series power supply for VCRs and TVs, Computer Systems and Battery powered systems.
